A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The object is illuminated by unstructured light and the object is covered by a textured surface. The invention also relates to methods for producing a wheat plant containing in its genetic material one or more transgenes and to the transgenic wheat plants and plant parts produced by those methods. Compressing the video data from the compression encoder and decoder circuit on the time axis in the time axis compression circuit makes the recording time of the video data shorter on the magnetic tape than the actual recording time of the video camera.
